Construction of a complete system for the recovery of water from an industrial tumbling process
Customer
The client is a galvanic company that has an internal tumbling process.
Objectives
Reduce disposal costs, Reduce the environmental impact of the production process, Reuse the distillate produced as part of the treatment process
01.
Opportunity
Recover and recirculate good quality industrial water for the tumbling process.
02.
Project
Feasibility study through analysis of disposal costs compared to the costs of recovery and valorization of the water product as a raw/secondary material.
03.
Solution
Treatment plant consisting of a sludge thickening/filtration process and a vacuum evaporation process for the recovery and reuse of water characterized by good salinity so that it can be reused in the process.
Liquid sent to the vacuum evaporator of the total treated volume.
Filter press sludge of the treated volume.
Concentrated product (consisting of soaps and inorganic salts) of the volume sent to the evaporator.
Distillate produced in the volume sent to the evaporator.
Analysis of the results
Total cost of treatment of tumbling water with vacuum evaporator approximately €85/ton.
Total cost of disposal of tumbling water as is approximately €110/ton.
The implementation of the vacuum evaporator treatment plant has demonstrated a clear economic and environmental superiority compared to the traditional solution for the disposal of tumbling water. With a treatment cost reduced from €110/ton to €85/ton, the company achieved an economic saving of 23%, while simultaneously improving its environmental balance.
In terms of sustainability, the solution adopted allows the reuse of the distillate produced within the production process, contributing to the creation of a circular model. This approach not only reduces liquid waste for disposal, but also promotes more efficient management of water resources, in line with European directives on the transition to more sustainable economies.
From an operational point of view, the vacuum evaporator has proven to be particularly effective in separating pollutants from water, allowing the recovery of a high-quality distillate that can be used in the production process. This solution therefore represents a concrete example of how technological innovation can reconcile economic and environmental objectives, while at the same time guaranteeing a competitive advantage on the market.
